The Aftershock is a Hardmode broadsword that drops from Earth Elementals. Upon hitting an enemy, it spawns a boulder that falls from the sky and pierces five enemies.

Its best modifier is Legendary.


  • The Aftershock is very useful for rapidly annihilating worm-like enemies, since the falling rocks can hit several segments.


  • Unlike most on-hit effects, the Aftershock's effect can be triggered by Target Dummies.
    • This will not work during boss fights.
